大贾庄铁矿跨河大桥桩基偏位的处理方法

根据大贾庄铁矿跨河大桥4号墩4-1#桩基偏位处理工程实例,针对桥梁桩基施工中产生的桩基偏位问题,通过计算桩基偏位受力情况,采用在4-2#和4-3#桩基增加连梁的处理方法,改善了偏位桩基偏心受力不利的影响,达到了在较短的工期内,安全、经济地处理好偏位桩基的目的.

Processing Method on Pile Foundation Deviation of Dajiazhuang Iron Ore River Crossing Bridge

According to the engineering examples of the treatment to Dajiazhuang iron ore river crossing bridge No.4 pier of 4-1# pile foundation deviation, in view of the problem of pile foundation deviation in construction of bridge, through the calculation of pile foundation deviation stress, the paper adopts a meth- od of increasing coupling beam with 4-2# and 4-3# foundation, which improves the adverse effect of ec- centric force of deviation pile, achieves the purpose of safety and economic treatment of the pile deviation in a short time.
